Abstract
Abstract A method is disclosed of forming a seam joining together two edges of a piece of fabric coated on one face with a water-impervious high frequency weldable plastics material, so as to form a water-impervious seam. In the method, the two edges are located together with the said coated faces facing outwardly, a binding strip is located over the said coated faces, the face of the binding strip in contact with the coated faces itself being coated with a high frequency activated material, and a radiofrequency field is applied to the seam to weld together adjacent said coated faces of the binding strip and the fabric. Certain forms of polyurethane and poly(vinyl chloride) are given as examples of high frequency activated materials. A novel seam is also disclosed.
